DETAILED DESCRIPTION OF THE INVENTION

The compounds of formula I wherein A is --(CH₂)nNR₉ R₁₀ can be preparedaccording to the following schematic flow chart ##STR7## where R isalkyl of one through two carbons, i.e. ketal or acetal functionality,and all the other terms are as defined above. When n is 1 in a compoundof formula I, it is preferred that X in structure II be bromo. When n is2 to 5, it is preferred that X be chloro.

The compounds of formula I wherein A is selected from group consistingof ##STR8## can also be prepared in accordance with the above flow chartby substituting ##STR9## wherein D, X, R₈ and R₁₃ through R₂₀ are thesame as above, respectively, for the straight chain compounds of formulaIV.

Step 1 can be performed in the absence of solvent but a solvent such asmethylene chloride, nitromethane tetrahydrofuran (THF), ethylether,carbon disulfide, benzene, or toluene is preferred. Preferredtemperature is about 25° but temperatures from 0° to 60° are acceptable.

Step 2 can be performed in the absence of solvent but use of a solventsuch as methyl, ethyl, propyl, or butyl alcohol, ethylene glycol,dimethylformamide (DMF), or dimethylsulfoxide (DMSO) is preferred. Anexcess amount of base such as triethylamine is used in step 2 to absorbthe acid produced.

The acid catalysts for step 1 include mineral acids and Lewis acids suchas HCl, HBr and H₂ SO₄, BF₃.Et₂ O, ptoluenesulfonic acid (pTsOH),trifluoroacetic acid (TFA), acetic acid, and SnCl₄.

The compounds (I) obtained can be recovered and purified by conventionalmethods, for example, extraction, chromatography, crystallization, andcombinations thereof.

The following is a preferred preparation for the 2 benzoxepines offormula I where n=2. ##STR10##

Step 1' is carried out in the presence of an acid scavenger, forexample, pyridine, and is a conventional acylation reaction.

Step 2' is performed in an aromatic solvent such as toluene, innitromethane or in a halocarbon such as methylene chloride. Othercatalysts such as SnCl₄ or FeCl₃ are usable but AlCl₃ is preferred.Temperature can range from 10° to 100°.

Step 3' may be conducted in non-polar solvents such as THF, ether, ortoluene.

The acid catalysts for step 4' are as described above for producing thecompounds of structure II.

The compounds (II) obtained can be recovered and purified byconventional methods, for example, extraction, chromatography andcrystallization.

The thiols of structure III (W═S) can be prepared from the alcohols viatheir bromides in accordance with the following flow chart, or by otherliterature methods for example, see Frank and Smith, J. Amer. Chem.Soc., 68, 2103 (1946). ##STR11## wherein n is 1 to 5 and a, b, R₁through R₈ and D are as above, and X' is chloro or bromo. The compoundswherein A is the branched alkylene chain can be made using theappropriate starting materials IVa, IVb, and IVc.

In step A, the alcohol of formula IIIa can be converted to the bromideof formula VI by various procedures known to those skilled in the art.For example, it may be reacted with phosphorus tribromide or hydrogenbromide as is described in J. March, "Advanced Organic Chemistry",McGraw-Hill, 1968, p. 343.

In step B the bromide of formula Q is reacted with a mercaptide, forexample sodium mercaptide, to give the thiol of formula IIIb.

In step C the thiol of formula IIIb is reacted with the appropriateacetal, ketal, ketone, or aldehyde in the presence of an acid catalystto give the halide of formula IIb.

The halide IIb can be reacted with amines to form the compounds havingthe formula I'b in the manner described above for the preparation ofcompounds of Formula I. ##STR12##

Similarly, by using the thiol IIIb with starting materials IVa, IVb orIVc followed by reaction with the desired amines there are obtained theappropriate 1-substituted 2-benzothiepins.

For the preparation of compounds of formula I wherein R₂ through R₇ arealkyl, halo, alkoxy cycloalkyl and b=0,1, the following reactions (1-4)can be followed as examples: ##STR13##

Each acid or ester can then be reduced by conventional procedures (e.g.with sodium borohydride-Ethanol) to the alcohol and subsequently treatedwith compounds IV, IVa, IVb or IVc to give the precursor1-(haloalkyl)-1-R₈ isochromans or benzoxepins which can then be reactedas described above with amines to give the corresponding formula Icompounds. When it is desired that W═S, the thiols can be prepared fromthe alcohols as shown in the flow scheme for preparing compounds offormula IIb.

The above reactions for placing substituents on the carbon alpha to theacid function in a chain are known in the art and are only given asrepresentative. They are not to be construed as limiting.

Reaction type (3) has been described in J. Amer. Chem. Soc., 98, 6750(1976).

Reaction type (4) is known in the art for alkylation at acidic hydrogenssites-this type of reaction can be found in Organic Syntheses (Wiley),Volume 50, p. 58 (1970).

Reaction type (5) can be carried out according to Katzenellenbogen, J.Org. Chem. 38, 2733(1973).

Compounds of formula I wherein A contains oxygen can be prepared inaccordance with the following flow diagram: ##STR14## wherein a, b, R₁through R₈ and NR₂₁ R₂₂ are the same as above, m and q are each one tothree and B' is selected from the group consisting of hydroxy, halo andthe group ##STR15## wherein R' is selected from the group consisting ofhydrogen, lower alkyl of from one to three carbon atoms, NO₂, halo andtrifluoromethyl.

The reaction of step 2a is preferably carried out with VII wherein B' ishalo, (preferred is chlorine) p-nitrobenzenesulfonyl, or other leavinggroup. When B' is hydroxy a prior sulfonation reaction is performed, forexample with p-nitrobenzenesulfonyl chloride, to give VII wherein B' isp-nitrobenzenesulfonyl; this compound then can be reacted with the amineas described below:

When B' is the group ##STR16## wherein R' is the same as above, thereaction of step 2a is conducted by using about 1-10 moles of amine toabout 1 mole of the compound of formula VII, preferably two moles ofamine to about one mole of the compound of formula VII. The reaction isconducted at a temperature of about 20° to 70° for a period of one to 40hours.

When B' is halogen, the reaction of step 2a is conducted in the presenceor absence of a solvent at a temperature of between 20° and 70° for aperiod of one to 40 hours. Solvents that can be utilized include, butare not limited to ethylene glycol, dimethyl formamide, (DMF),tetrahydrofuran, dimethyl sulfoxide (DMSO), with DMF being the preferredsolvent.

The above reaction may be carried out in the presence or absence of asolvent at a temperature between 20° and 50° for a period of about onehour to ten hours. Solvents that may be used include DMF, THF, methylenechloride and toluene.

The preferred solvent is methylene chloride. Suitable acid acceptorsinclude the trialkylamines, e.g. triethylamine, inorganic salts, e.g.barium carbonate, and DBU. The preferred acid acceptor is triethylamine.

Compounds of formula VII where B' is halo are prepared in accordancewith the following schematic flow chart. ##STR18## where a, b, m, q, R₁through R₈ and W are the same as above.

The reaction may be carried out in the absence or presence of a solventand at a temperature of about 20° to 100° for 20 to 120 hours. Organicor inorganic bases such as barium carbonate, triethylamine or ethyldi-i-propylamine can be used as acid scavengers.

The compounds of formula VIIIa wherein q is two or three may also beprepared from compounds of formula VIIIa wherein q is one in accordancewith the following flow diagram ##STR19## where X is halogen, q' is oneor two and a, b, m, W and R₁ through R₈ are the same as above.

This reaction may be carried out in the absence or presence of asolvent. It is also desirable to use an acid acceptor and to run thereaction for about 20 to 120 hours at a temperature of 20° to 100°. Sameacid scavengers as above can be used.

The compounds of formula VII wherein B is hydroxy and q is one areprepared by reacting a compound of formula II' with ethylene glycol. Thereaction is conducted in the presence of an acid acceptor such asdi-isopropylethyl-amine at a temperature of between 20° and 100° for aperiod of about 20 to 120 hours.

In all of the procedures described herein, the desired product orintermediates can be obtained from the reaction mixture utilizingstandard methods, for example, extraction, chromatography,crystallization and combinations thereof.

The compounds of formula Ic, wherein b is zero, m is 1, and R₁ -R₅, R₈,R₂₂, NR₂₁, a, q, and W are as defined above, are advantageously preparedby the route described in the following chart: ##STR20## wherein R" isalkyl of one through three carbon atoms, inclusive.

Step a is advantageously carried out in the presence of acids such asBF₃ Et₂ O; trifluoracetic acid, p-toluensulfonic acid, in solvents suchas nitromethane or methylene chloride, at 0° to about 30° C.

Step b is carried out by use of conventional reducing agents, e.g.lithium aluminum hydride in non-polar solvents such as tetrahydrofuranat 0° to 30° C.

Step c is advantageously performed by reaction of an easily cleavableether (e.g. tetrahydropyranyl ether) of the desired haloalkoxyalkanol onthe alkoxide of compound II' at 20°-100° C. in a compatible non-polarsolvent followed by cleavage of the ether under acidic conditions togive the alcohol VIII' ; this can then be subsequently converted to theamine product using conditions described above in the process forconverting compounds of formula VIIIa to their corresponding amines.

Pharmaceutically acceptable acid addition salts of the compounds (I) areprepared by reacting the free base of a compound of formula (I) with astoichiometric amount of an acid, such as hydrogen chloride, hydrogenbromide, hydrogen iodide, sulfuric acid, phosphoric acid, acetic acid,propionic acid, butyric acid, lactic acid, citric acid, succinic acid,benzoic acid, salicylic acid, pamoic acid, phthalic acid,cyclohexanesulfamic acid, and the like.

This invention relates also to pharmaceutical dosage unit forms forsystemic administration (oral and parenteral and rectal administration)for treating hypertensive mammals, including humans. The terms "dosageunit form" as used in this specification and in the claims refers tophysically discrete units suitable as unitary dosages for mammaliansubjects, each unit containing a pre-determined quantity of theessential active ingredient, i.e., a compound (I) or a pharmaceuticallyacceptable acid addition salt thereof calculated to produce the desiredeffect, in combination with the required pharmaceutical means whichadapt the said ingredient for systemic administration. Examples ofdosage unit forms in accordance with this invention are tablets,capsules, orally administered liquid preparations in liquid vehicles,sterile preparations in liquid vehicles for intramuscular andintravenous administration, suppositories, and sterile dry preparationsfor the extemporaneous preparation of sterile injectable preparations ina liquid vehicle. Solid diluents or carriers for the solid oralpharmaceutical dosage unit forms are selected from the group consistingof lipids, carbohydrates, proteins and mineral solids, for example,starch, sucrose, kaolin, dicalcium phosphate, gelatin, acacia, cornsyrup, corn starch, talc and the like. Capsules, both hard and soft, areformulated with conventional diluents and excipients, for example,edible oils, talc, calcium carbonate, calcium stearate and the like.Liquid preparations for oral administration ae prepared in water oraqueous vehicles which advantageously contain suspending agents, such asfor example, ethanol, sodium carboxymethylcellulose, acacia, polyvinylpyrrollidone, polyvinyl alcohol and the like. In the instance ofinjectable forms, they must be sterile and must be fluid to the extentthat easy syringeability exists. Such preparations must be stable underthe conditions of manufacture and storage, and ordinarly contain inaddition to the basic solvent or suspending liquid, preservatives in thenature of bacteristatic and fungicistatis agents, for example, parabens,chlorobutanol, benzyl, alcohol, phenol, thimerosal, and the like. Inmany cases it is preferable to include isotonic agents, for examplesugars or sodium chloride. Carriers and vehicles include vegetable oils,ethanol and polyols, for example, glycerol, propylene glycol, liquidpolyethylene glycol, and the like. Any solid preparations for subsequentextemporaneous preparation of sterile injectable preparations aresterilized, preferably by exposure to a sterilizing gas, such as forexample ethylene oxide. The aforesaid carriers, vehicles, diluents,excipients, preservatives, isotonic agents and the like constitute thepharmaceutical means which adapt the preparations for systemicadministration.

For animals, food premixes with starch, oatmeal, dried fishmeat,fishmeat, fishmeal, flour and the like can be prepared.

For CNS disease, a daily dose of 5 to 600 mg is indicated,preferentially 10 to 200 mg; in unit of two or three subdivided doses,and the exact amount is adjusted based on the weight, age, and conditionof the patient.

The pharmaceutical dosage unit forms are prepared in accordance with thepreceding general description to provide from about 0.5 mg to about 100mg of the essential active ingredient per dosage unit form. The amountof the essential active ingredient provided in the pharmaceutical dosageunit forms is based on the finding that the effective amount ofcompounds of the invention and acid addition salts thereof, forobtaining a hypotensive effect in mammals is within a range from about0.1 mg per kg to about 35 mg/kg, preferably 0.3 to 15 mg/kg.

The active ingredients of this invention can also be compounded incombination with other ingredients. The amount of such other activeingredients is to be determined with reference to the usual dosage ofeach such ingredient. Thus these novel compounds can be combined withother hypotensive agents such as α-methyldopa (100-250 mg); withdiuretics such as hydrochlorothiazide (10-50 mg); peripheralvasodilators such as hydralazine (10-100 mg); tranquilizers such asmeprobamate (200-400 mg), diazepam (2-10 mg) muscle relaxants, such ascarisoprodol (200-400 mg).

The tranquilization activity of the new compounds of formulae I andtheir pharmacologically acceptable acid addition salts are tested inmice as follows:

Chimney test: [Med. Exp. 4, 145 (1961)]: The test determines the abilityof mice to back up and out of a vertical glass cylinder within 30seconds. At the effective dosage, 50% of the mice failed doing it.

Dish test: Mice in Petri dishes (10 cm. diameter, and 5 cm. high),partially embedded in wood shavings, climb out in a very short time,when not treated. Mice remaining in the dish for more than 3 minutesindicates tranquilization. ED₅₀ equals the dose of test compound atwhich 50% of the mice remain in the dish.

Pedestal test: The untreated mouse leaves the pedestal in less than aminute to climb back to the floor of the standard mouse box.Tranquilized mice will stay on the pedestal for more than one minute.

Nicotine antagonism test: Mice in a group of 6 are injected with thetest compound. Thirty minutes later the mice including control(untreated) mice are injected with nicotine salicylate (2 mg./kg.). Thecontrol mice show overstimulation, i.e. (1) running convulsions,followed by (2) tonic extensor fits; followed by (3) deaths.Pretreatment with an active sedative or tranquilizing compound protectsmice against (2) and (3).

TESTING FOR ANXIETY

Prolongation of Hypoxic survival: Pretreatment of mice exposed to thestress of progressive hypoxia and hyperapnia with anxiolytics results ina prolongation of survival. Male CF-1 derived mice are used in thesestudies. Thirty minutes after intraperitoneal pretreatment (test agentsuspended in 0.25% methylcellulose or vehicle alone, 1 cc/100 gm bodyweight) the mice are placed singly in 125 ml. Erlenmeyer flasks. Thereceptacles are tightly stoppered and the survival time (time fromstoppering to the last respiratory effort) of each animal noted. Eachcompound is tested at three or more doses spaced at 0.3 log intervals.Six mice are used per dose with six vehicle injected controls runsimultaneously. The mean (15-18 minutes) and standard deviation (1-2minutes) of the survival time for the vehicle treated mice are used toconvert the data to a quantal form in the following manner. All survivaltimes that differed from the mean of the controls by more than 2standard deviations are scored as a drug effect. ED₅₀ s are calculatedby the method of Spearman and Karber (Finney, D. J., Statistical Methodin Biological Assay, Hafner Publ., Co., N.Y. 1952).

The novel compounds of formula I and pharmacologically acceptable acidaddition salts thereof also have antidepressant activity.

The main function of an anti-depressant is to return the depressedindividual to normal function. This should be carefully differentiatedfrom psychic stimulants such as the amphetamines which producedoverstimulation in the normal individual.

Many different methods have been and are used to evaluate antidepressantactivity. In general these methods involve antagonism to a depressantsuch as reserpine or tetrabenazine or a synergistic increase of thetoxicity of certain compounds (i.e., yohimbine or3,4-dihydroxyphenylalanine) and comparison of the drug action of the newcompound with other known antidepressants. No single test alone candetermine whether or not a new compound is an antidepressant or not, butthe profile evidenced by various tests will establish thatantidepressant action is present. A number of such tests are describedcribed below.

Hypothermic tests with oxotremorine[1-[4-(pyrrolidinyl)-2-butynyl]-2-pyrrolidinone].

Oxotremorine (as well as apomorphine and tetrabenzzine) produceshypothermic responses in mice. This response is blocked byanticholinergics and antidepressants such as atropine and imipramine.

Oxotremorine produced a very pronounced hypothermia which reaches a peak60 minutes after administration. When administered at 0.6 mg/kg the bodytemperature of a mouse is descreased about 13° F. (when the mouse iskept at room temperature). This temperature decrease is antagonized byantidepressants, e.g., desipramine, imipramine, and amitriptyline.

The present compounds are tested as follows. Groups of four male miceweighing 18-22 g (Strain CF1, Carworth Farms) are injectedintraperitoneally with the test compound prepared in 0.25%methylcellulose and placed in plastic cages. Thirty minutes later 1mg/kg oxotremorine hydrochloride is injected subcutaneously. The miceare placed in a refrigerator maintained at 19° C. Thirty minutes laterthe intraperitoneal temperature is measured using a thermistor probe. Anincrease of 4° F. in the body temperature of the treated mouse(oxotremorine and test compound) over the control mouse (oxotremorinetreated only) is indicative of antidepressive activity.

The same compounds were also tested for potentiation of yohimbineaggregation toxicity. The LD₅₀ of yohimbine hydrochloride in mice is 45mg/kg, i.p. Administration of 20 mg/kg. of yohimbine hydrochloride isnon-lethal. If an antidepressant is administered prior to the yohimbinehydrochloride (20 mg/kg) the lethalitv of the yohimbine hydrochloride isincreased.

Eight male CF1 mice, 18-22 g, are injected with yohimbine hydrochloridein saline solution. After four hours the LD₅₀ s are determined. Groupsof eight mice are injected with the antidepressant 30 minutes before theadministration of yohimbine hydrochloride [YCl] (20 mg/kg). No mice oronly one mouse is killed from 20 mg/kg of [YCl]. If [YCl] isadministered in the presence of an antidepressant an increase in thetoxicity of [YCl] is found. The ED₅₀ is the dosage of test compoundwhich causes 50% of the mice to die.

Also the compounds are tested for the potentiation of apomorphinegnawing. A group of 4 mice (male, CF1, 18-22 g) are administered thetest compound intraperitoneally 1 hour prior to the subcutaneousinjection of apomorphine hydrochloride 10 mg/kg. The mice are thenplaced in a plastic box (6×11×5 inches) lined at the bottom with acellophane-backed, absorbent paper. The degree of damage to the paper atthe end of 30 minutes is scored from zero to 4. The scores 2 to 4indicate that the compound is a potentiator of apomorphine in this test.

Results in the above tests show that the compounds of formula I and thepharmacologically acceptable acid addition salts thereof can be used asantidepressants, sedatives, and antianxiety drugs in mammals to achievenormalcy in the depressed or anxious individual.

As antipsychotics-neuroleptics the compounds of formula I and theirpharmacologically acceptable acid addition salts can be used in dosagesof 1-300 mg/day and preferably 5-250 mg/day in oral or injectablepreparations, as described above, to alleviate psychotic states such asschizophrenia, manic depressions, etc. The exact amounts to be given aredependent on the age, weight, and condition of the patient.

The following examples and preparations describe the manner and processof making and using the invention and set forth the best modecontemplated by the inventor of carrying out the invention but are notto be construed as limiting.

All temperatures are in degrees centigrade.

The compounds of this invention show potent hypotensive activity on oraladministration to normotensive rats. A 4 mm Hg decrease in Mean ArterialPressure when measured at 4 hours or 24 hours after administration of 50mg/kg of drug is considered statistically significant. By far themajority of the compounds of this invention give blood pressure drops ofgreater than 8 mm Hg, and some of them have the desirable feature ofbeing of longer duration of action (beyond 24 hours).

Also, in the accepted test methodology for neuroleptic (antipsychotic)activity, such as the inhibition of amphetamine aggregation toxicity(Weaver and Kerley, J. Pharm. and Exp. Therap., 135, 240 (1962)) thedose required to inhibit death of 50% of animals previously challengedwith amphetamine gives a measure of the activity of the drug; the lowerthe dose required, the more potent the drug. Mice are injected with thedrug subcutaneously. Inhibition at a dose of 25 mg/kg is consideredsignificant. The potent compounds of this invention show a desirablelevel of death inhibition at a dose of 15 mg/kg or less.

In other accepted tests for antipsychotic activity, as, for example,reversal of hypothermia caused by oxotremorine again the potentcompounds of this invention showed reversal at a dose of less than 15mg/kg; reversal at a dose of 40 mg/kg is considered significant.

PREPARATION 1A7,8-Dimethoxy-1-chloroethyl-1,3,4,5-tetrahydro-2-benzoxepin

To 19.86 g. (0.149 moles) of AlCl₃ in 200 ml of CH₂ Cl₂ was added 14.20ml (0.149 moles) of 3-chloropropionylchloride. The mixture is stirredfor 15 minutes under a N₂ atmosphere and then 38.00 g (0.0992 moles) ofthe 3-chloropropionate of 3-(3,4-dimethoxyphenyl)propanol in 200 ml ofCH₂ Cl₂ is added over a period of 15 min. from a dropping funnel. Afterstirring at room temperature for 30 min., the reaction mixture is heatedat reflux for an additional 3.6 hours. The reaction mixture is thencooled and aqueous sodium bicarbonate is added until gas evolutionceases. The organic layer is filtered through sodium sulfate and takento dryness. The residue is chromatographed using 20% EtOAc:Skellysolve Bas eluant.

A tetrahydrofuran solution of3-chloro-4',5'-dimethoxy-3'-[3-(3-chloropropionoxy)propyl]propiophenone(about 40 g.) is added dropwise to an ice-cooled mixture of 7.3 g. oflithium aluminum hydride in tetrahydrofuran. After stirring for 20minutes the reaction mixture is treated with 7.3 ml water, 7.3 ml 15%sodium hydroxide, and 21 ml water. The resulting suspension is filteredthrough Celite and the salts washed with ether. The filtrate isextracted with brine and the organic phase is filtered through sodiumsulfate and concentrated.

The crude product is dissolved in 500 ml of methylene chloride andtreated with 13 g of p-toluenesulfonic acid monohydrate. After stirringfor 10 minutes the blue-green solution is extracted with aqueous sodiumbicarbonate and brine. The organic layer is filtered through sodiumsulfate and taken to dryness. Chromatography on silica gel with 20%ethyl acetate in Skellysolve B gives 14.7 g of7,8-dimethoxy-1-chloroethyl-1,3,4,5-tetrahydro-2-benzoxepin.

Following the procedure of preparation 1A, but substituting theappropriate 3-substituted-phenylpropanol for3-(3,4-dimethoxyphenyl)propanol, the 1-chloroethylbenzoxepins of Table1A were prepared.

PREPARATION 8 2-[(1-methyl-7,8-dimethoxyisochroman-1-yl)methoxy]ethanoland derivatives.

Ethyl pyruvate (1.00 g, 0.0086 m), 3,4-dimethoxyphenylethanol (1.57 g,0.0086 m), and, 1 ml of BF₃ etherate are stirred at 25° C. in 20 ml ofnitromethane for 45 minutes. The mixture is dissolved in methylenechloride and extracted with aqueous sodium bicarbonate. The organicphase is dried (sodium sulfate), concentrated, and chromatographed onsilica gel to give 1.4 g of6,7-dimethoxy-1-methyl-1-carboethoxyisochroman. A 0.5 g sample of thisis dissolved in ether and treated with 100 mg of LAH. After 10 minutes,the mixture is quenched with ethyl acetate and partitioned between 1 Naqueous sodium hydroxide and CH₂ Cl₂. The organic phase yields 0.34 g of6,7-dimethoxy-1-methyl-1-hydroxymethylisochroman. This is dissolved inTHF and treated sequentially with sodium hydride and theno-tetrahydropyranyl chloroethanol. The adduct, upon treatment with acidand water, yields2-[(7,8-dimethoxy-1-methyl-isochroman-1-yl)methoxy]ethanol. In themanner of Preparation 7, this can be converted to its benzenesulfonates##STR21## Furthermore, 2-[(1-methylisochroman-1-yl)methoxy]ethanols,with various substituents on the isochroman ring, can be prepared byusing the appropriate phenyl ethanols whose substituents, R₁ -R₅ (videsupra), are analogous to those substituents of the isochromans of Table3.

From these compounds, the corresponding substituted benzenesulfonatescan be prepared.

Furthermore, by reacting appropriate phenyl ethanols with varioussubstituted 2-keto esters, the R₈ substituents of the isochroman ring(vide supra) can be varied and the disclosed R₈ substituents can thus beincorporated in the ring system.

Furthermore, various 1-hydroxymethylisochromans can be first treatedwith tetrahydropyranyl chloroethoxyethanol and then with acid and waterto yield the corresponding 2-[2-((isochroman-1-yl)methoxy)ethoxy]ethanol.
